To a/ZZ whom, it may concern:

Be it known that I, FRANK L. FoRsrER, a

necting several parts together so that they.

can be readily separated, more particularly in such instances Where twoparts are to be maintained in `line with each other and at right anglesto a third part, as the ends and a horizontal part of a sectional case.

Incarrying out .the invention the ends or :vertical parts of a case orother article of furnitu're are constructed to provide abuttingshoulders and have recesses constructed to receive the cross-head of acouplin g. The horizontal member has a straight or flush end and arecess for a plate which projects from the cross -head, as well asaboltreceiving aperture and a recess which intersects such aperture, thesame being intended to receive a washer and a nut, there also beingprovided a block constructed to close the bolt and washer receivingrecess, the block being held in place b v the resilient ends of thewasher, all as will be hereinafter referred to or specifically pointedout in the claims.

In the accompanyingdrawings, which illusstrate one embodiment of myinvention, Figure 1 is a vertical section showing the application of thecoupling to the end and horizontal members of an article of furniture.Fig. 2 is a horizontal. section taken through the horizontal member ofan article of furniture and through the filling-block and washer. Fig. 3is a perspective view of the metallic parts of the coupling separated,and Fig. 4C is a perspective view of the block used for closing thewasher and nut receiving recess.

In the. embodiment of the invention illustrated, A A'indicate the endpieces of an article of furnature, as a section of a knockdown orseparable bookcase, and the adjacent ends of such parts are providedwith shoulders a a', so constructed that when the shoulwill be providedfor the passage therethrough of a plate or horizontal member of thecoupling. The ends A 'Al-rh'ave recesses a2 a3 for the reception of thecross-head of the coupling.

The horizontal member B of the case or article of furniture has a recessb, a bolt-receivis intersected by a recess B' of sulcient size toreceive a washer and nut, and a tool or wrench which is used to turn thenut to draw the parts together.

head c, one face of which is serrated, and from the central portion ofthe cross-head there projects a plate C', the end of which carries abolt O2.

from one of the walls of the recess B' and will bear upon the ends oi' aiilling-block E, so as to retain the same in the recess. The iillingf,and the block has a projecting portion e,

which will fill the space above the washer.

With the construction shown it will be noted that the end pieces A A.abut against the by such construction when the nut is turned by a wrenchto draw the parts together there is no liability of splitting-orbreakingthe end portions with which the serrated head of the curely heldin place by impinging against the resilient ends of the washer and thewalls of the recess B'.

A coupling constructed as shown is coube tightened when desired byremoving the block.

I claim as new, and desire to secure by Letters Patent, is

1. In a knockdown article of furniture, two parts having recesses sopositioned that when the partsare placed end to end the recesses willbein alinement, a third part having a recess and intersected by a nutand washer receiving recess, in combination with a coup- Having thusdescribed my invention, what' ders abut against the adjacent end aspace' ing aperture b', which projects therefrom and 6o The couplingmember C consists o f a cross- D refers to a washer, which is curvedlon- 7c gitudinally, so thatthe ends will spring away block E is cutaway centrally to span the nut straight end of the horizontal part B andthat 8o lcross-head engages, and the block will be secealed by the partswhich it connects and may 9o cess, a bolt-aperture connected with thererco ling comprising a cross-head, a plate which projects therefrom, abolt formed integral with the plate and a nut and washer, substantiallyas shown.

2. In combination with a coupling comprising a cross-head, a plate whichprojects centrally therefrom and a bolt formed integral with the plate,one of the parts to be connected having a recess for a Washer and nut,such recess being intersected by a bolt-receiving aperture, of a blockwhich spans the bolt and closes the recess, and a washer having endportions which engage the block on. each side of the bolt to retain theboltin the recess.

3. The combination with a coupling member comprising a cross-head, aiiat member which projects at right angles from the same,

third part having a recess and an aperture which extends therefrom forthe reception of the flat member and the bolt of the coupling,substantially as shown and for the purpose set forth.

In testimonywhereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
